I really resonate with the "Acceptance" section. I came to a similar realization, that having strong negative emotions about the pain just made everything worse. Stress causes inflammation which doesn't help, and only hurts the situation.
As for actual strategies to manage emotions, I would strongly recommend reading books about REBT (the precursor to CBT) such as "How To Stubbornly Refuse To Make Yourself Miserable About Anything-yes, Anything!" It's honestly been life-changing, and I think a lot of folks here would appreciate the rational approach to adjusting one's beliefs, feelings, and actions. Being able to avoid unnecessary negative emotions, and irrational beliefs that upset you, can be a superpower.
